The peace talks in Paris dragged on for years
without achieving anything. By 1972 the communists felt strong enough to launch
another all-out attack on the cities of the South, similar to the Tet
Offensive. This attack was more successful than the Tet Offensive but the
communists were still not able to conquer the main centers of population.

After the offensive of the summer of 1972,
neither side could see any hope of victory and the peace talks started to make
some progress. At last in January 1973 a cease-fire was agreed and the
Americans started to take their troops home.

The fall of the South: 1975

The American forces pulled out soon after the
cease-fire agreement was signed. This ended US involvement but it did not end
the war. Fighting soon resumed between the communists and the Southern forces.
Two years after the agreement in Paris the North launched another major
offensive against South Vietnam in March 1975. This time, relying only on South
Vietnamese troops and without American air support, the Saigon government was
not able to resist.

The Vietcong and the army of the North swept
victoriously through the South. The war effectively ended on 29 April 1975 when
the communists captured the southern capital of Saigon. American TV viewers
watched in horror as thousands of south Vietnamese people fought to get on the
last US helicopters out of Saigon.

After Vietnam: detente and a loss of
confidence

American failure to contain communism in
Vietnam led to a deep re-assessment of policy towards the communist world.
American leaders had been shocked by their failure in Vietnam. The cost has
been enormous: 55,000 dead American soldiers and billions of dollars spent.
This huge commitment had achieved nothing.

Communist governments had taken power not only
in North and South Vietnam but also in the neighboring states of Cambodia and
Laos. In addition, Americans had lost the confidence in their mission as the
world's leading nation.

The American President who took the US out of
the war was Richard Nixon. Together with his adviser, Henry Kissinger, Nixon
developed a new foreign policy for the post-Vietnam world. This became known as
'detente' and it involved striving for agreement and peace with the communist
world.
